Tickets are open in November / December, although it can be tricky to get one. If you are interested please mention it so here so we can try to have some spare tickets maybe. They start around 120 EUR for the whole 4 day congress.

I have been at 33c3 (Hamburg) and 34c3 (Leipzig) and it’s a not-to-miss event. As the dates are around Christmas and New Year’s eve (27-30th Dec) you should expect to plan ahead. It’s suggested to fly out to Berlin and take a train from there to Leipzig (1-2h, 40-80 EUR return)

For something “official” (well, umm… as far as official can go on a C3 you could apply for a so-called assembly. Assemblies can be about anything to present a group or community and gather around a table, a booth, an installation, … Take a look at the call for participation (CfP) in the Assemblies section and watch out for when the 35C3 Wiki will come alive, where assemblies can be registered then. To get an idea see last year’s 34C3 Assemblies.

I might have gotten ahold of a voucher. If you are interested to buy a ticket right away with a credit card let me know so we can circulate it quickly within the community. Afaik, it should be around 100-120 EUR. Up to 2 tickets can be bought with a voucher (at least the past years it has been like that).

FWIW I will be in Leipzig this year for 35c3. Feel free to ping me, if you want to meet there for a chat – or some assistance in navigating the congress. Although I havent been in Leipzig last year, I have been attending a few previous editions in Hamburg and Berlin, which gives me some ideas on what to expect.
